This may occur for reasons including your breach of these Terms, violation of applicable laws, or any conduct we deem harmful to the Services or our interests.

Termination or suspension may include the immediate deactivation or deletion of your account and the forfeiture of any associated data. Upon termination, all rights and licences granted to you under these Terms will cease immediately. You remain liable for any obligations incurred before the termination, and all provisions that by their nature should survive termination shall continue in effect.
